SEAL-HASP.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filedliebruary 1c, 1913. Serial no. 7423451.

My invention relates to improvements in ,seal-hasps and moreparticularly it relates to seal-hasps that are adapted to be used onrailroad freight cars to fasten and seal their doors.

The object of my improvement is to provide a seal-hasp which shall bestrong, durableysimple in construction and reliable in its operation andwhich is adapted to be sealed with a seal that may cost but little tomake, such'seal being readily accessible for quick inspection; and afurther object of my improvement is to provide seal-hasps one of whichcannot possibly be unhasped without breaking some part of it or makingit clearly observable that its seal has been mutilated. I attain theseobjects by devices illustrated in the accompanying drawings, wherein-Figure 1 is a view in side elevation of a seal-hasp containing myinvention as applied to a fragment of a door frame of a car, Fig. 2 is aview in front elevation of the same in which some parts are shown invertical-section on broken line as, w of Fig. 1, Fig. 3 is a view invertical-section of the same (on broken line 1 1 of Fig. 2) except thattwo movable parts are shown in side elevation, Fig. 4 is a fragmentaryview of the same in front elevation (with some parts shown invertical-section on broken line an m of Fig. 1) but wherein itsboltshaft is turned to a position that is 90 degrees distant from theposition of the same bolt-shaft as shown in Fig. 1, Fig. 5 is a view inhorizontal cross-section of the same on broken line a, a of Fig. 4, andFig. 6 is a'view in horizontal cross-section of a boltshaft, on brokenline w, 'w of Fig. 4.

Like reference numerals indicate like parts throughout the drawings.

Referring to the drawings, 7 represents a door-post of a railway freightcar upon which is fastened. thebase 8 of a seal-hasp by bolts 9, 9.Extending outwardly from said base 8 and integral therewith is thebolt-shaft barrel 10 and a bolt-socket 11, said bolt-socket 11 isprojecting through the oblong hole 12 of a hasp strap 13 a fragment ofwhich is shown in Fig. 2 and which may be supposed to be fastened upon afreight car door not shown. A bolt-shaft 1-1, as shown in Fig. 1, isdisposed within the bolt shaft barrel 1.0 to extenddownwardly to projectinto the bolt-socket 11 to secure the hasp-strap 13 in its position onthe bolt socket 11. j

Figs. 1, 2 and 3 illustrate the position of the shaft-bolt 14 when a cardoor to which the device is applied is locked and sealed,

the. sealing being effected by a seal made of thin sheet metal,preferably of thin tin plate, in the form of a narrow strip which isprovided in its central portion with an elongated hole 16, said sealbeing disposed diametrically through the said bolt-shaft 14: so thateach of its end portions projects from its side of the bolt-shaft 1 1for a suitable distance to afford surface upon which may be stamped orinscribed distinctive numbers orcharacters. The bolt-shaft 14c isprovided witha longitudinal slotted hole 18 that extends through it fromside to side in a place at right angles with the hole 17 and in aposition to intersect said hole 17 and within such slotted hole 18 isdisposed a pawl 19 which is pivoted by a pin 20 to swing freely withinsaid slotted hole 18, said pawl 19 being provided with a projectingtongue 21 that is adapted by its position with relation to the hole 17to project through the oblong hole 16 of a seal 15 when such seal 15 isinserted in the hole 17 to assume its position therein, as shown in Fi.2, whereby said seal 15 may be securely locked within the hole 17 bysaid tongue 21, as more clearly indicated in Fig. 3. To in sert the seal15 into and through the hole 17 the bolt-shaft 14 (when in thecircumferential position shown in Fig. 4) ismoved to its farthestdownward extent to extend its end through the bolt-socket 11 which willbring the pawl 19 low enough to permit its wider end to be projected outof its slotted hole 18 far enough to remove its tongue 21 from aposition to obstruct the insertion of the seal 15. (but such position isnot illustrated in the drawings) and after a seal15 is inserted thebolt-shaft 1 1 is turned cir- .cumferentially for a distance of 90degrees and then drawn upwardly until it assumes the position shown inFig. 3, whereupon another pawl 22, which is pivotally disposed withinanother slotted hole 23, is caused by in a rectangular shaped hole 17that extends l a spiral compression spring 24, to project an angularcorner into a recess 25 in the frame of the bolt-shaft barrel 10, asshown in Fig. 3, whereby the bolt-shaft 1% may not be moved downwardlyagain until the seal 15 is broken or cut to remove it from the hole 17,and said bolt-shaft 1 L cannot be raised from its position, as shown inFig. 3, without mutilating the seal 15 since the pawl 19 projectsoutwardly from the slotted hole 18 and held there by the seal 15 so thatthe wider end of said pawl 19 cannot be raised into the boltshaft barrel10 without cutting or mutilating the seal 15 and furthermore, thebolt-shaft 14 cannot be turned circumferentially from its position asshown in Fig. 3, since the end of a screw 26 is disposed to projectwithin the slotted hole 18 at all times except when the boltshaft 1 1 isin its lowest position at which time the end of said screw 26 willregister with a circumferential slot 27 which extends for a distance of90 degrees, or more, from the slotted hole 18, and except when thebolt-shaft 14 is raised to its highest position when the end of thescrew 26 will register with another longitudinal slot 28 disposed at apoint near the lower end of the bolt-shaft 1 1 to extendcircumferentially for a distance of more than 90 degrees from theslotted hole 18. Thus with the boltshaft 14 disposed in the position,shown in Fig. .3, to secure the hasp-strap 13 in its position on thebolt-socket 11 such bolt-shaft 14: cannot be moved in any directionwithout cutting or mutilating the seal 15 to an extent that would bereadily observable.

hen the bolt-shaft 14: is not sealed by a seal 15 and it is desired toretain it in its uppermost position as shown in Fig. 1, it. is onlynecessary to turn it 90 degrees from the position from which it is shownin said Fig. 4e whereupon the angular corner of the pawl 22 in responseto the action of the spring 24 will project more and more outwardly fromits slotted hole23 as it follows the cam-like surface 29 of the upperend of the barrel 10 as illustrated in Fig. 5, until the pawl 22 reachesthe position indicated by the dotted lines in said 5, in which positionthe said. angular corner of the pawl 22 will engage with the fiatsurface 30 on the end of the barrel. 10, thus to retain the bolt-shaftit in its highest position whereby the haspstrap 13 may be placed overthe bolt-socket 11 and obviously to shoot the bolt downwardly into thesocket 11 it is only necessary to turn the shaft-bolt 14 in acontraclock-wise direction to the position shown in Fig. 5, whereuponthe cam-like surface 29 will force the pawl 22 inwardly so that thebolt-shaft 14, may pass to its lowest point to lock the hasp-strap 13 onthe bolt-socket 11 and at such lowest point the seal 15 may be insertedwhereupon the bolt-shaft 14c may be 1 turned back 90 degrees and raisedto the position shown in Fig. 3, there to be locked by the pawl 22 withrespect to downward movement and by the end of the screw 26 with respectto circumferential movement and by the pawl 19 with its tongue 21 andthe seal 15 with respect to its upward movement and hence saidbolt-shaft 14 may not be withdrawn from the bolt-socket 11 withoutdestroying or observably mutilating the seal 15. I have shown a turn-pin31 secured in the u per end portion of the bolt-shaft 14. to facilitatethe manipulation of said boltshaft 1 1.

In Fig. 6, I have shown by a view in crosssection on line to, w of Fig.at, the bolt-shaft 14 and the circumferential slot 28.

Obviously many modifications of the various parts of my invention, maybe made, in the form and dimensions without departing from the spiritthereof.

lVhat I claim is:

1. in a seal-hasp of the class described, the combination with abolt-shaft barrel which is associated with a supporting base plate, of abolt-shaft socket, a bolt-shaft adapted to be moved in a lengthwisedirection within said bolt-shaft barrel to cause it to enter andwithdraw from said boltshaft SOCkut said bolt-shaft being provided witha longitudinal slot, a pawl which is provided with a tongue thatprojects from one of its edges and which is pivotally disposed within.said longitudinal slot in said bolt-shaft, a hole in said bolt-shaftdisposed to extend therethr'ough from side to side with its axis atright angles with said longitudinal slot and to register with the pathof said tongue of said pawl, and sealing means adapted to be disposed insaid hole normally to maintain said pawl in a position wherein a portionof it will project outwardly from said longitudinal slot in saidbolt-shaft whereby said bolt-shaft may not be withdrawn from saidbolt-shaft socket without causing said pawl to mutilate said seal.

2. In a seal-hasp of the class described, the combination with abolt-shaft provided with recesses extending longitudinally therein, of apawl pivotally disposed within one of said recesses, retractile meansass-ociated with said pawl and said bolt-shaft and disposed to adapt itto cause said pawl normally to project for a suitable distance outwardlyfrom said bolt-shaft, another pawl pivotally disposed within another ofsaid recesses, and sealing means associated with said last named pawland said boltshaft whereby such last named pawl may be caused normallyto project outwardly from said bolt-shaft.

3. In a seal-hasp of the class described, the combination with asuitably supported bolt-shaft barrel, of a bo'ltshaft socket, ahasp-strap adapted to be locked on said boltshaft socket, a bolt-shaftadapted to be moved in said bolt-shaft barrel to cause it to lock andunlock said hasp-strap on said bolt-shaft socket said bolt-shaft beingprovided with pawls pivotally disposed in association with it so thatone of said pawls may be actuated to sustain said bolt-shaft in anuppermost position where it is disengaged from said bolt-shaft socketwhile the other of said pawls is adapted to be caused to assunie aposition whereby it may prevent an upward movement of said bolt-shaft insaid bolt-shaft barrel and sealing means adapted to maintain said lastnamed pawl in such position as will prevent said u ward move- 15 ment ofsaid bolt-shaft in said bolt-shaft barrel.

In witness whereof, I hereunto subscribe my name this first day ofFebruary A. D.,
